Description

  The present invention is an energy-saving panel heater for snow melting that operates by detecting snowfall by incorporating a thin snow sensor into the thin panel heater for snow melting.

Panel heaters for snow melting have long been sold as retrofit-type snow melting heaters.
Usually, the cap of the attached lead cable is inserted into an outdoor outlet, and the power is supplied. This is a small power heater for easily carrying out snow melting in a small area. However, the power supply time was 100% power supply while the power supply was plugged into the outlet, and the power supply was almost always supplied during the winter period, and the power supply was almost always supplied.

  For this reason, even though it is a snow heater with a small area and low power, it is energized even when there is no snowfall, and the energization time is extremely long, which wastes power and pays a larger electricity fee than expected. .

  Furthermore, many people have accidentally overheated the snow-melting panel heater due to an increase in ambient temperature, direct sunlight, etc. from spring to summer due to forgetting to unplug from the outlet after the snowfall period.

As a remedy, it is effective to control the power of the panel heater for snow melting by sensing snowfall. However, there are few small and thin products of snowfall sensing sensor, and the price is expensive. If it is attempted to incorporate this into a snow-melting panel heater, the thickness of the snow-melting panel heater will be as large as several tens of millimeters or more, and it will be difficult to install it easily. Did not.

  The problem to be solved is that a thin snowmelt heater and a thin snowfall sensor are installed in a single snowmelt panel, the heater is turned on when snowfall is detected, and the power is turned off at the end of snowfall. And a method of sequentially connecting snow melting panel heaters according to the snow melting area.

  The present invention makes it possible to produce a thin, lightweight, and strong panel by manufacturing a snow-melting panel heater from a high-strength, lightweight material such as FRP (reinforced plastic), and inside the sheet-like snow-melting panel. Incorporating a heater, an electrode part that senses snow melting water with a thickness of about 1 to 2 mm on a part of the surface, and an electrode part to melt snow and create snow melting water when there is snowfall on the electrode part The development of a panel heater for snowmelt that incorporates a snowfall detection sensor with a set of auxiliary heaters with a sheet thickness of about 0.5 to 1 mm to be preheated. By combining a controller that obtains and controls signals, the simplicity of the snow melting panel heater has been further improved, and energy saving, safety and durability have been improved.

  The thin snow melting panel heater device with a snow melting sensor of the present invention incorporates a snow melting sensor into the snow melting panel heater that can be easily installed at any place where snow melting is required, and activates the snow melting heater only during snowfall. By eliminating unnecessary power consumption and reducing the operating time of the snow melting heater, the life of the heater is extended, and the heater is not operated except during snowfall to prevent accidents such as overheating and safety. Can be increased.

In order to reduce the thickness of the panel, use materials such as FRP (reinforced plastic) to increase the strength and reduce the weight. For the snowfall sensor, use a glass epoxy substrate as the core material to reduce the thickness. The copper foil on the board is etched to form electrodes, and the copper foil is nickel-plated to create a durable thin snowfall sensor.
By using a sheet-shaped sheet heater as a preheater, the thickness of the sensor part should be about 2 to 2.5 mm, and the thickness of the panel incorporating the snow melting heater and the snowfall sensor should be several millimeters. Can be done. The object was achieved by configuring a snow melting heater system by combining a controller for controlling the power supply of the thin panel heater for snow melting.

  FIG. 1 is a sectional view of an embodiment of the present invention, and FIG. 2 is a top view thereof. The sensor 3 for snowfall in the figure is closely attached to the upper surface of the heater for melting snow, and the surface of the sensor for snowfall is flush with the surface of the FRP (reinforced plastic) exterior material 1 in the figure. FIG. 4 is a sectional view of the snowfall sensor unit.

  For this reason, the preheating heater of the snowfall detection sensor is set to a heating value that does not overheat the sensor section even when the snow melting heater operates, or the controller turns off the preheating heater when the snow melting heater operates. Is set.

  The thin panel heater with a snowfall detection sensor of the present invention is completely waterproof, and because it is lightweight, it can be put on the top of the roof eaves and used for melting snow on the roof, or simply laid on a passage or veranda etc. As shown in Fig. 6, one snow-melting panel heater with a snowfall detection sensor can be used, depending on the length or area required for snow-melting because the power supply cables are attached to both ends of the panel heater. And several panel heaters without a snowfall detection sensor shown in FIG. 5 can be used side by side.

  One end of the power cable is terminated by performing terminal processing (insulation processing), and the other end is connected to a controller to supply power. A signal cable from the snow sensor is also connected to the controller. In addition, a temperature sensor is installed to accurately distinguish between snowfall and rainfall.

  When a panel heater for snow melting is installed on an entrance porch or a passage, if the thickness of the panel is required, a heat insulating material can be attached to the back surface of the heater for snow melting to have a cross section as shown in FIG.

  The snowfall sensor can be used as a mere moisture sensor when the temperature setting is changed, so it can also be used as a floor drying heater, such as a kitchen floor, where it could slip and fall if it gets wet. I can do it.
